CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 429,051, dated May 27,1890.

Application filed December 5, 1889. Serial No. 332,616. (No model.)

To all whom it may concern:

Be it known that I, NELsoN NEWMAN, of Springfield, in the county ofSangamon, State of Illinois, have invented new and useful Improvementsin Oar-Couplings; and I do hereby declare that the following is a full,clear, and exact description of my invention, which will enable othersskilled in the art to which it pertains to make and use it, refer- IOence being had to the accompanying drawings, forming a part thereof,

My invention relates to an improvement in car-couplings; and it consistsin the peculiar construction and combination of devices, that r 5 willbe more fully set forth hereinafter, and

particularly pointed out in the claims.

The object of my invention is to provide simple and effective means forautomatically coupling cars and for uncoupling the same from either sideor from the roof of the car with safety, and which is further adaptedfor use in coupling or uncoupling cars when in position on switches, andto be operated in connection with cars provided with the com- 2 5 monform of pin-and-link coupling.

In the accompanying drawings, Figure l is anend elevation of a carprovided with my improved coupling. Fig. 2 is a bottom plan View of myimproved car-coupling. Fig. 3 is 0 an invert-ed longitudinal sectionalview of the same, looking in the direction of the arrow. Figs. 4, 5, and6 are detail views. Figs. 7, 8, and 9 illustrate modifications adaptedfor passenger-cars.

5 On the end of the car A is arranged a lever 0, having the slot 0', inwhich the pivot works. A slide-bar B is arranged transversely on the endof the car in guides 17, has longitudinal and a slight verticalmovement.

in the said guides, and at the ends of the slide-bar are handles 12 Onthe under side of the slide-bar, near one end, is a notch b, which isadapted to engage a pin or stop 19 when the slide-bar is at one limit ofits movement to lock said slide-bar in that position,

for the purposes to be presently stated.

Arranged longitudinally under the car are parallel sills E, the ends ofwhich project beyond the ends of the car, and are connected by plates hon their lower sides and cross bars H on their upper sides. At the endsof the cars cross-plates h connect the sills on their upper and lowersides. The extreme ends of the sills are flared or beveled outward ontheir opposing inner sides. Arranged between the sills, at the endsthereof, are hooks D, having inwaixlly-extending arms D, and having thepivots d, which are in central openings in the cross-plates h. Springs 6have their outer ends bolted to the inner 6o sides of their respectivesills, and the free ends of said springs bear against the hookarms D andserve to normally retain the latter in the position shown in Fig. 2. Theouter ends of the hooks are slotted and provided with vertical openingsintersecting with the slots, and thereby adapted for the reception ofthepins and links in common use for coupling cars. A shaft K is pivoted inopenings in each cross-plate 7L and crossbar H, and is provided withbroadened flattened arms or keys k which project in opposite directions,and normally lie snugly between the couplinghooks when two cars arecoupled together, and being of such slight thickness 7 5 as to enablethe shoulders of the said coupling-hooks to be engaged notwithstandingthe interposition of the flattened arms or keys. At the upper end ofeach shaft K is attached a crank-arm having a pin or handle k, which isarranged between a pair of projecting pins 70 on the proximate slide-barB. The upper portion of the lever O works in a slot 9 in a guide-plateG, attached to the roof of the car at the end, and the lower end of saidlever is pivoted by a pin 0 to a standard 0 which is attached to theslide-bar. The latter maybe moved endwise either by moving one of itshandles from either side of the car or by operating the lever C from theroof. 0

The operation of my invention is as follows: When two cars are to becoupled, the abutting ends of the two draw-hooks D, Fig. 5, one on eachcar, impinge against each other, so as to compress the spring c, Fig. 2,5 which bears against the arms D of each draw-bar until the hooked endsof the drawhooks D pass each other, when the spring reacts, causing thehooks to engage. To uncouple the cars, the operator, standing at theside of the car, takes hold of the handle 19 and pushes the slide B inthe direction shown by the arrow, which causes the pins k to pressagainst the pin 7;, thereby turning the crank-lever K and the attachedwing or arm k so as to force apart the draw-hooks D and permit the carsto separate. To uncouple from the roof of the ear the operation is thesame, except that the operator on the footboard F takes hold of theupper projecting end of the lever C and pulls the lever toward him,which gives the proper motion to the slide-bar B. To prevent thecoupling of cars on switches or elsewhere where coupling may not bedesired, the draw-hook D is secured in the uncoupled posit-ion by movingthe slide-bar 13 until the notch d hooks over the pin (Z and firmlylocks the slide-bar B and the connected mechanism. The slide-bar B isunlocked either by pulling upward the upper end of the lever C or bylifting 011 the handle b at the end of the slide-bar adjacent to the pinb or by depressing the handle I) at the other end of the slide-bar.

I will 110w describe a modified form of my invention in which thecoupling devices are adapted to be used on passenger-cars. In Figs. 7and 8 the slide-bar I3 is shown ar ranged under the car-platform A andin the guides Z), which latter are bolted to the end of the car. Theends of the slide-bar are presented to openings A in the steps A so thatthe handles D of the slide-bar may be readily grasped and the slide-baroperated in the manner before described. By thus arranging the slide'barthe latter is disposed entirely out of the way, and the same otters noobstruction. As shown in Fig. 9, the guides b are arranged in ahorizontal position under the platform, and the slide-bar is arrangedflatwise.

Having thus described my invention, I claim 1. The combination of thespring-pressed pivoted draw-hooks, the pivoted flattened arms or keys karranged against the neck of one draw-hook and adapted to lie betweenthe same and the head of the companion draw-hook, the thickness of thesaid flattened arms or keys being less than that of the shoulders of thedraw-hooks, for the purpose set forth, substantially as described.

2. The combination of the spring-pressed pivoted draw-hooks, the pivotedflattened arms or keys L arranged between the neck of one hook and thehead of its engaging companion, and the crank-arm attached to the saidflattened arms or keys, whereby the latter may be turned, for thepurpose set forth, substantially as described.

The combination, in a car-coupling, of the pivoted engaging draw-hooks,the pivoted flattened arms or keys 7.: arranged between them and havingthe crank-arm, and the slidebar mounted on the end of the car andconnected to the said crank-arm, substantially as described.

4. The combination, in a ear-coupling, of the pivotedengagingdraw-hooks, the pivoted flattened arms or keys arranged betweenthem and having the crank-arm provided with the pin 7r, and theslide-bar on the end of the car and having the pins 7a engaging said pin7.7, for the purpose set forth, substantially as described.

5. In a car-coupling, the pivoted drawhooks, the spring, the shafthaving the arm or key to disengage the draw-hook, and provided, further,with the crank-arm, the slidebar connected to the crank-arm, and thelever connected to the slide-bar, all in combination, substantially asdescribed.

(3. In a car-coupling, the combination of the sills, the cross-platesconnecting them, the draw-hooks arranged between the sills and havingthe pivot in the cross-plates, the spring bearing against one side ofthe draw-- hook arm, and the shaft having the flattened wings or armsbearing against the same side of the draw-hooks, substantially asdescribed.

In testimony that I claim the foregoing I hereto append my signatn re.

NELSON NEWMAN.
